IMPRoveMENT N sPeie-EsrENoNlNG MACHINES.

To all whom it may concern Be it known that we, GoDnRnY E. GULP and MAT THEW Fume, of Lockhaven,in theeountyof Clinton and State of Pennsylvania, have invented a new and improved Spoke-tenoning Machine; and we do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawingforming a part of this specification, in which- Figure l is a side elevation with a partial section and.

Figure 2 is a plan view. 'This invention consists in the construction ot'` an apparatus for holding spokes down while the plane is operating on them;

Also in the construct-ion of aguide-way for the plane to run in, such guide-way having recesses for the spokes to rest in, and adjustable supports for regulating the position of the spokes while the plane is forming tenons on them, and the construction of an auxiliary beam placed at, a convenient distance from the guideway and providedl with side clamps for holding' the smaller ends of the` spokes;

` Also in theeombination with such guide-way and auxiliary beam of aV brace placed betweenthe same, and provided withclamps, and designed for preventing the 'spokes from springing under the vertical clamping apparatus.

In the drawing- D is the frame of the machine. i

A is ythe `guide-wayfor the plane, placed preferably at one side oi` the frame-work.

B is the auxiliary beam, placed at theopposite side of the'frame-work. A y

`b are the transverse recesses for th'elrecept-ion ofthe spokes, cut in both the guide-wayandf beam B.

a are the supports, `placed lengthwise of the recesses b, in suitable slots, and resting ou the heads of vertical screw-bolts', o, which extend downward' through ar'rns, fr, projecting horizontally from vertical standands, s, extending downward from the under side of the guideway A,'so that, on the application of a wrench to the screw-bolts, the supports a may be raised or loweredin the recesses b to suit diierent thicknesses of spoke.

. To the outside of beam B are attached, by setscrewhs, slotted clamps, cl, which may be advanced lengthwise ofthe beam against the sides ofthe spokes,

or drawn backward to accommodate wider spokes;

v To the inside ofthe guidcway A are attached, by setscrews, slotted plates, c, one to each recess, which may be moved lengthwise ofthe guide-way for the purpose ofregulatiug the inclination of the spoke to the guideway according as the slant of thc shoulder should be which is to be formed on the spoke.

These vparticulars having been attended to, by a movement of the lever i to the right the plate C is lowered, through the action of the pin protruding from the lever into the slot e,- and 'this movement depresses the holder e, in which .is pivoted the semi-circular clamping-frame h., slotted in the middle of its bow for purposes of adjustment, and provided with feet t, whichv are forced down on kthe spoke by the aforesaid movemeut of the lever t', and rrnly hold it without at the same timel indenting its surface.

The plane is then run through the guide-way and across the spoke, as many times as may be necessary to form the tenen on one side.'

A scale is inscribed, at thev side of the right recess, transversely of the bottom of the guid-way, to assist the operator in determining the length of the tenen. Y In the recesses 11, at the right, each spoke is placed first, and after the tenon has been cut on one side the same spoke'is transferred to the recesses b, at the left, and turned over so that the shoulder just formed may abut against the inner side of the support a in the left recess, and 'insure the formation of a shoulder on the upper side'of the spoke with the' same slant as that already formed.

At'the same time a fresh spoke is placed in the recesses at vthe right, both spokes being held at the same time by the semicircular clamp-frame h., withoue foot t on each, the set-screw u being turned outward so as to leave the frame free to adjust itself to both Y spokes at once.

When only one spoke is in the machine, the frame-vl h is -clamped to the holder e in such manner as to 0011- fine that one. v

Thespringdever G is jointed tothe top of the vbolt c, which, being vexteriorly threaded, may be turned up or down so as to give the lever afnlcrurn of a height proportioned to the thickness of thespolie or other article under, operation.

The movement of the lever 'i to the right or left immediately clamps or un'clamps the spoke with the greatest ease.

.To prevent the pressing apparatus from springing the spokes, a b1'ace,mz., is placed lengthwise `between the guide-way and side beam, which brace is supported Y by screw-bolts passing through its ends and mounted in the cross-bars E E of the frame, so as to be vertically adjustable to the same extent with the su'pporif" ing plates a, and proxfided with slotted plates, a, at-

tached by set-screws to the top of the brace, for clamping the sides'f'the spokes in the same Ina-nner as the plates d; lhis bracenud its plates also serve to support spokes tooshortto rest both upon the guide-way A and the side bea-m13.

The lever 'i has, nearits lower end, a slot, w, through which the bolt passes that slides in the slot e. By

raising or lowering the lever O in 'the slot w, the leverage of the lever e' is varied so that it presses the 'clamp-frame h downward with more or less force.

Having thus described our invention,

y What we claim as new, and desire to secure by Letters Patent, is-

1. The spring-plate O, hangin g holder e, clamp-frame h, feet t, and lever i, pivoted in a suitable standard7 and provided with a pin working in .the slot l of the springplate,wher 1 all these parts are constructed, arranged, and operating as described. v

also provided with transverse recesses b and with adjustable side-clamps el, and the spring-plate G, hanging holder e, clamp-frame h, and lever fi, when all these parts are constructed to operate as described.

3. The adj ustable brace m provided with sliding clamps a, the recessed'guide-wayA provided with the adjustable supports. a, and the recessed side-beam B provided with the side-clamps (l, when all these partsare combined and arranged as described'.
